From Sonos- We're sending out a software update tomorrow. If you're no longer running iOS6 on the iPhone or iPad you use with your Sonos, you'll be good to go. However, if you're still controlling your system with a device that's running iOS6, here are a few changes you should be aware of.
What won't change: The way you play music. Browse your library and music services. Group rooms. Adjust and mute your volume.
What you'll no longer be able to do: Set up a new Sonos system. Add new players to your current system. Change your system settings. Add or remove music services. Adjust the EQ.
Not sure which iOS version you're running? Let's find out.
If you're currently on iOS6, now would be a great time to upgrade. You can also find links to the latest version of the Sonos Controller app for any compatible device on Sonos.com.
If you have any additional questions or concerns, please contact your installing dealer or Sonos.com/support.
